A person is driving a car. The car&driver have combined mass of 1000kg. The car is travelling at 25m/s when it hits the car in front then it's brought to rest. How much energy was transferred from the car in bringing it to rest?
- How does the energy flow diagram look like for this question? Is the arrow pointing from the car to the car in front? Could you draw them if you can?

A m 1 =1000kg car driving at V1i =1.5 m/s on a parking lot collides with a car of mass m 2 =1200.0 Kg sitting at rest. The first car hits and sticks to the second car. Calculate the following: What is the speed of the two entangled cars after Collison? What is the kinetic energy (K 1 I )of the first car before Collison? What is the kinetic energy (K 2 I )of the second car before Collison? e)...

Consider someone driving down the highway at 70 miles per hour (31.3 m/s). The total mass of the driver and their car (as well as everything else in the car) is 1300kg. A) How much work must friction do to make the car stop? I got −6.37×10^5 J B) A tree suddenly falls on the highway 60m in front of the car, and the driver just barely manages to stop before hitting the tree. What is the magnitude of the...

A person driving her car at 49.0 km/hr approaches an intersection just as the traffic light turns yellow. She knows that the yellow light lasts only 1.80 s before turning to red, and she is a distance D = 35.0 m away from the near side of the intersection. If she decides to stop, how far from the intersection will she come to a stop? The intersection is W =11.0 m wide. Her car's maximum deceleration is -5.70 m/s2. Ignore...

A driver is driving once again from Nogales to Tucson on I-19. Suddenly a roadrunner darts out into the middle of the road. It doesn’t see her at first, because it is focused on a tasty lizard it’s trying to catch. She is initially traveling at 110 km/hour, the roadrunner is 30m in front of her when she applies her brakes, and the brakes decelerate the car at 9 m/s2. She slams on her brakes, and the sound of squealing...

You are driving to the grocery store at 25 m/s . You are 110 m from an intersection when the traffic light turns red. Assume that your reaction time is 0.70 s and that your car brakes with constant acceleration. -How far are you from the intersection when you begin to apply the brakes? -What acceleration will bring you to rest right at the intersection? -How long does it take you to stop? A rock is tossed straight up with...

Full Solution Problem for Chapter 06 (FS06)-Using Generalized Momentum-Impulse equation driving 20 m/s when it sees a deer (at rest in the road). The driver of the car hits the brakes, but it's too late- he hits the deer. The deer sticks to the car (sorry, deerl) and they skid forward as the car br has a mass of 500 kg and the deer has a mass between the car's tires and the road is 0.&. (Friction is much smaller...

There was a car accident. Someone stopped and the person
behind them rear ended them. The car that stopped slid away about
30 feet and the car that did the rear ending stopped right about
where the collision happened. Was this a perfectly inelastic
collision? Why or why not?
A perfectly elastic collision is one in which kinetic
energy is conserved. How exactly is kinetic energy not conserved
though? Sometime KE can be used up compressing/bending things and
making heat,...

2. Suppose a car travels 108 km at a speed of 20.0 m/s, and uses
2.20 gallons of gasoline. Only 30% of the gasoline goes into useful
work by the force that keeps the car moving at constant speed
despite friction. (The energy content of gasoline is 1.3 ✕
108 J per gallon.)
(a) What is the force exerted to keep the car moving at constant
speed?
N
(b) If the required force is directly proportional to speed, how
many...
